Still waiting for Standard bank to resolve my life cover complaint

I am still waiting for Standard bank to resolve my complaint regarding a life cover policy that I believe was not properly explained to me when it was sold. Standard bank previously advised me that they were investigating the matter and promised to provide me with feedback between 7 and 11 September. I also followed up by email, but I have still not received a response. I understand that investigations can take time, but I am disappointed that I have had to keep following up without receiving clear communication. I am asking Standard bank to please provide me with a proper update and explain what action they intend to take regarding my complaint. I would appreciate a clear and final response rather than having to repeatedly follow up.
